ocaml-gsl (OCaml bindings for GNU Scientific Library) currently
fails to link to atlas:
+ /usr/bin/ocamlfind ocamlopt -g -I lib -linkpkg -package bigarray -I lib -I
examples lib/gsl.cmxa examples/blas_ex.cmx -o examples/blas_ex.native
/usr/lib64/atlas/libsatlas.so: undefined reference to `dlarfy_'
/usr/lib64/atlas/libsatlas.so: undefined reference to `slarfy_'
/usr/lib64/atlas/libsatlas.so: undefined reference to `clarfy_'
/usr/lib64/atlas/libsatlas.so: undefined reference to `zlarfy_'
collect2: error: ld returned 1 exit status
However this only happens with the very latest atlas that was built by
binutils 2.29 (atlas-3.10.2-18.fc27.x86_64). It doesn't occur with
the previous version of atlas (atlas-3.10.2-16.fc26) even though there
seems to have been no change in atlas.
$ nm -D /usr/lib64/atlas/libtatlas.so | grep larfy
U clarfy_
U dlarfy_
U slarfy_
U zlarfy_
I looked in /usr/lib64 on my development machine which has atlas
installed but there is no .so* file that I can find which defines
these symbols. I also couldn't work out where in the atlas code
(which is a bit strange) these references are used.
Hence the question: Is this breakage in atlas? binutils?
